The Western world is succumbing to an obesity crisis, in the United States more than two thirds of adults are considered to be overweight or obese, and the problem is not much better in the United Kingdom. But why is it that some people are not succumbing? Is it because their diet is different, or is there some other genetic or scientific answer?
Why Are Thin People Not Fat? Is a 2009 BBC Horizon feature which attempts to answer that question using research from the world of medical science and presents some interesting answers, and they aren’t all about exercise and diet. At the heart of the research is an overeating experiment which attempted to ascertain why some of those who consumed too much food gained lots of weight, whilst others struggled to bulk up.
